I COIN-FREE!) MECHANISM.

Application filed August 4, 1827, S rial N0. 2 2, and in Great Britain February 15, 1927.

This invention relates more especially to coin-freed mechanism for use with an operated sliding part such as the drawer ofv a cigarette or sweetmeat delivery machine or theslider of ajticket delivering machine and has for its object to provide a cheap and compact form of mechanism.

This invention comprises a striking face of an operated sliding part which moves in such a way as to encounter the end of a slider having a slanted face and sliding in'a car-- rier which is yieldingly mounted, and the slider is pressed towards the strikingface of the operated sliding part by a relatively weak spring. Rigid with the slider is a rod adapted to move endwise across-the coin chute. If therefore an attempt is'made to operate the sliding part without inserting a coin, the striking face of the sliding part simply presses forward the slanted face of the slider and engages with'an abutment of the carrier whereby further operation -1s stopped. If, however, a correct coin 1s 1nserted, it prevents movement of the rod across the coin chute so that the rod then holds the slider and its'slanted face against the pressure of the striking face of the operated sliding part, so that the said striking face rides up the said slanting face and presses down thecarrier until it rides over the upper surface thereof. J The invention is described with reference to the drawings herewith, of which Figure l is a longitudinal sectional view showing an operated sliding part and coinfreed mechanism by which it is locked, the apparatus being sho'wnin the normal locked position. i Figure 2 is a view corresponding to F gure 1, but showing the parts in the position they assume if an attempt is made to operate the slider without inserting a coin.

Figure 3 1s a view corresponding to Figure 1; but showing the parts in the position they assume when the sliding. part is first operated after the insertion of a coin. Figure): is a section taken on the line 4, 4, of Figure 3 and looking in the direction of the arrow of that figure. Figure 5 is a view of the apparatus show ing the parts in the position they assume when the operated sliding part is drawn out to its fullest extent. 7 In these drawings :A is the operated part sliding in a guide C and having adownwardly extending striking face a. B is a. carriage inthe formof a lever pivoted at b to the guide C and having a coin chute c" and a sliding rodd to which is clamped an L shaped bracket 6 with a slanting face f. The rod d with its bracket 6, is arranged to slide in guides of the carrier B and is constantly pressed in a rearward direction by means of a relatively weak spring 9 against a stop h of the carrier. 7' 7' (see especially Figure 4) are two stops carried upon. the lower ends of lugs 7c 70 which are rigid witli' the guide C and serve the double purpose of limiting the upward movement of the carrier B by coming against the front of the coin-chute thereof, and of keepingthe coin in place while the slidingpart A is operated. The carrier B is constantly pressed in an upward direction by means oftwocoil springs M (one only of which is shown) which connect at their lower ends to lugs n of the carrier and at their upper ends to lugs p of the guide C.

Q is a set screw for clamping the bracket e on the rod and allowingfor its adjustment thereon. It will be seen that the rod (2 is pointed at itsforward end, andthat in the normal position of the apparatus it just reaches to the coin chute 0.

If an attempt is made to operate the sliding part A without inserting a' coin,-the

striking face it engages the slanting face f of the bracket e and presses it and the rod cZ back against the force of the spring 9 which is comparatively weak, and the point of the rod simplymoves across the coin chute to the position shown in Figure 2, so that the striking face 7 of the'sliding part A encounters the rear end of the carrier B whereby it is stopped from further move:- ment; 7

On pushing back the sliding-part Aand inserting a coin thelatter goes downthe coin-chute and comes'to rest upon the stops- 7 7- slanting face as before but the bracket 6 will not yield forwards because the rod 03 If-now the said part A beoperated, 10o the striking face a will press upon, the

is prevented from moving across the coin chute c by the presence of the coin therein.

Consequently continued forward movement of the sliding part A presses down the bracket 6 and with it the carrier B, the striking face a riding up on to the top of the carrier B all as shown in Figures 3 and no thereon.

Having fully described 5. The pressing down of the carrier B inrelation to the guzde C causes the coinchute c to move forward in r'elationto the stops j and allows the coin to fall from the coin-chute as soon as the striking-faced has moved forwards clear of the bracket 6, and has ceased to'eXert forward pressure sume their normal position in relation to the carrier B. hen the sliding: partA is moved backto its normal position the'parts go back to the position shown in Figure 1.

"It will now'be seen-that a very delicate setting of the rod cl in relation to the. bracket 6 will have the. effect of discr1minating between different thicknesses 'of coins inserted, because the rod may be so set in.

relation to the bracket that a' coin uwhich exceeds a certain thickness will be stopped by the point of the rod, while acoin which is too thin, by allowing a certain amount of forward movement of the rod in relation to the coin-chute may cause the striking face a to encounter the rear end of the carrier C and prevent further forward movement. of

the sliding'part, A. The stops can be so arranged that they will allow a coin of too smalla diameter to pass clear through, and the width of the coin chute may be such as to render-it impossible to insert a coin which exceedsa predetermined diameter.

The reason why the rod '(Z is pointedlis" that, if a washer'is inserted in the 'coinchute in lieu of a coin, the point of the rod will pass through the washeriand the parts will remain locked.- 'Also the point will pierce cardboard or soft metal and .thePartsj what I claim. and desire to secure byLet ters Patent is I 1. In coin-freed apparatus, a relatively moving part, a striking face of such part, a

, yielding slide with a slanting rear end against wh ch saidstriking face engages, a

guide for the relatively moving part, a carrier yielclingly mounted in relation to the said guide and carrying said slide, a stop rigidly mounted in relation to the guide for limiting the upward movement of the carrier, a coin-chute into which the forward end of the saidslide is adapted to pass, means by which the coin is stopped in the coin chute opposite the'slide whereby the latter is prevented from forward movement under the action of the said striking face so that said striking face rides up the said Ihe bracket 6 and rodd then as my invention, 7

8. In. coin-freed apparatus, a relatively moving, part, a striking face of such part, a. y elding-slide having a slanting rearend against which said striking face engages, a guide for the relatively moving part, a carrier pivotally mounted inrelation to the said guide and carrying saidslide, a coin-chute inthe carrier into which chute the forward end of the said slide is adapted to pass, a

a pair of stopsprojecting into the coin-chute whereby the coin is stopped opposite the slide and said stops passing out from under the coin .to release it. when the carrier has moved .a predetermined distance.

4. In coin-freed apparatus, a relatively moving'part, a striking face of such part, a-

sliding spring-pressed rod with. a pointed forward end, a bracketadjustably mounted on said rodand having a slanted rear end against which said striking face engages, a guide for the. relatively moving part, a carrier yieldingly mounted in relation to the said guide and carrying said slide, a stop rigidly mounted in relation to .the guide for limiting the upward movement of the carrier, a coin-chute-into which the forward end of the said slide is adapted to pass, means'bywhich the vcoin is stopped in the coin chute'opposite the slide whereby the latter is prevented from forward movement under the action of the said striking face so that the latter rides up the said slanting end of the slide-depressing the carrier and riding th'ereover, and means by which the coin is subsequently released. 5. In coin-freed apparatus, a relatively moving part, a striking face of such part, a yielding slide with a. slanting rear end against which said striking face engages, a guide for the relatively moving part, a car rier pivotally mounted in relation to the said guide and carrying said slider, means by which said carrier is constantly pressed in an upward direction, a stop rigidl mounted in relation to the guide for limiting the upward movement of the carrier, a coinchute in the carrier into which chute the forward end of the said slide is adapted to pass, means by which the coin is stop ed in the coin chute opposite the slide where y the latter is prevented from forward movement under the action of the said striking face so that the latter rides up the said slanting end 10 of the slide depressing the carrier and riding thereover, and means by which the coin is subsequently released.
